Transaction Support in JsStore

[erraisahmad]

Hi,

I am working on a web app which stores some offline data in IndexedDB.
I am integrating this library into my project. I have a requirement of performing multiple operations tables in a single transaction, so that the operations can be rolled back, if any error occurs in any operation.
Indexed Db supports transaction as follows

var transaction = db.transaction();   //API for representation only
 var store = transaction.objectStore();  // //API for representation only 
 request = store.add();     //API for representation only

Does JsStore support transactions where I can perform multiple CRUD operations?
Can you please let me know if I can achieve similar functionality using JsStore?

Hello,

I would like to know if it is possible to check if a transaction is in progress? The following example, I use JSStore in Angular 5 as cache and if the component was destroyed, a write process should be executed. At the same time, a component is initialized to this data record in read mode. Because of the fact that asynchronous execution occurs, this leads to the error.

Greetings

Hi

I am not able to understand the situation. Can you explain more ?

also what do you mean when you say - to check if a transaction is in progress ? I mean you call the transaction api and then transaction is started.

Let me know what do you think?

Hi,

thanks for your response. Is there a possibility to see get the state of a process. e.g. like transaction, insert, delete, update?

I need this for Angular 5 Livecircle. First Component is in ngOnDestroy and update table. Second Component is in ngOnInit and read in the same table older data because the update table is not finished.

[ujjwalguptaofficial]

so you want to know what query is currently being executed right ?

[theS3ns]

Correct or whether one is executed at all

[ujjwalguptaofficial]

yes you can get that. connection object holds the list of request that will be executed so the request which is being executed is - the first value in the array.

Hope this helps. Let me know.
